Chapter 3 — Configuring the CV30
CV30 Fixed Mount Computer With Windows CE User’s Manual 41
Intermec recommends using security with wireless networks to
prevent unauthorized access to your network and to ensure the
privacy of transmitted data. Authentication by both the network
and the user are required elements for secure networks.
Using WPA Security
Wi-Fi Protected Access (WPA) is a strongly enhanced,
interoperable Wi-Fi security that addresses many of the
vulnerabilities of Wired Equivalent Privacy (WEP). Instead of
WEP, WPA uses Temporal Key Integrity Protocol (TKIP) for its
data encryption method.
Currently, WPA satisfies some of the requirements in the IEEE
802.11i draft standard. When the standard is finalized, WPA will
maintain forward compatibility.
WPA runs in 802.1x (Enterprise) mode or PSK (Pre-Shared Key)
mode:
• In Enterprise mode, WPA provides user authentication using
802.1x and an Extensible Authentication Protocol (EAP).
That is, an authentication server (such as a RADIUS server)
must authenticate each device before the device can
communicate with the wireless network.
• In PSK mode, WPA provides user authentication using a
shared key between the authenticator and the CV30. WPA-
PSK is a good solution for small offices or home offices that
do not want to use an authentication server.
To use WPA security, you need:
• an authentication server (Enterprise mode only).
• an access point with an 802.11 b/g radio that supports WPA.
• a CV30 with the 802.11b/g radio and the 802.1x/WPA
security option.
The CV30 also supports Wi-Fi Protected Access 2 (WPA2) if you
are using Funk security. WPA2 uses an Advanced Encryption
Standard (AES) for data encryption.
